Re: [MBZ] Compressor woes, post mortem.

Well, my A/C compressor had well and truly killed itself.  Indy says it
appears to have gotten a slug of liquid.  He got the supplier to 
warrant it


That would imply that it probably has a broken reed valve.

Royce,

I have occasionally run the heater coming to work and the A/C going
home.

Thanks, Marshall,

I don't usually have to worry about running the AC during the
winterhere
in Houston we have plenty of warm winter days  ;-)

Actually it's important that the AC compressor be turned on and run
every few weeks (for a few minutes) ALL winter. That prevents seal
hardening and greatly increases compressor life. It's not necessary for
the later systems (124/201, later 126) that use the Nippondenso
compressors that function whenever the system is in defrost (and the
temperature is in the correct range).
